Probably not the right forum, but figured anyone lurking here might have a direction.
I have a Jacuzzi hot tub that i would love to monitor chemical status for. Already have a temp sensor that i setup, but would love to have something that told me pH levels, chlorine (it uses a spa frog and enhanced shock), calcium, etc.
and of course looking for something much cheaper than what some of these control devices seem to need.
any ideas appreciated. i need a new project :-)
